As the acreage burned by the Mendocino Complex fires exceeded that of the Carr Fire, its evacuation zone expanded to cover a large swath north of Clear Lake.

As of Friday morning, CalFire reported that the Ranch Fire was at 112,226 acres and 28 percent containment and the River Fire at 41,512 acres and 50 percent containment. That total — 153,738 — outstrips the Carr Fire near Redding by more than 20,000 acres.

On Thursday evening, mandatory evacuation orders were issued for the communities of Spring Valley, Long Valley and High Valley, between Lucerne and Indian Valley Reservoir in Lake County.

The new evacuation area extends to the scar of the Pawnee Fire (in black on the map above), which burned 15,185 acres near the reservoir in June and July.

CalFire said the Mendocino Complex’s two fires, which started within an hour of each other last Friday, have destroyed 41 homes and 47 other structures and are threatening 9,200 buildings.
